review text: The authors considered unsteady motion and evolution of density inhomogeneities in a developed fluidized bed of ferromagnetic solid particles. The bed was taken subject to the action of a specified external magnetic field. The authors tried to develop the model of inhomogeneity caused due to particle concentration difference throughout the bed, as a spherical cluster of particles whose boundary is the surface of discontinuity of the distribution of the solid-phase concentration. They have studied two cases: (i) a varying density of the surface of discontinuity, impermeable to solid-phase particles, and (ii) a discontinuity with inflow or outflow of dispersed particles. The effect of the external magnetic field and magnetic properties of the particles on the velocity of motion of inhomogeneities through the bed, their steady-state size and life times was evaluated.
